Be Quick or Be Dead (10): Complete the mission on Hard difficulty in less than 10 minutes.

Tychus Findlay and Raynor are ruinited and it feels so good.

Tychus Findlay has tracked down Raynor and presented him with a business proposition: collecting alien artifacts for his client. Since Raynor wants the Dominion gone, and Findlay wants to collect credits, it turns out to be the perfect match.

Build an Army

You'll start this mission with a small base already established. Your goal is simple: build up a force of Marines and eliminate the Dominion. We went a little overboard by how many Marines we really needed (one can never be too prepared). Build a bunch of SCVs to collect the Minerals faster, build a Refinery to start collecting gas (this will allow you to purchase a Tech Lab for your Barracks, enabling you to create Medics)

We went a little overboard on unit production. But too many Marines is better than not enough.

If you built a force of close to 20 Marines you should have an ample amount of troops to not only rescue the rebels to the west (the distress signal will automatically happen a few minutes into the match), but once you do rescue them, your forces will be combined and your infantry will turn into a small army, capable of rolling into the base without much resistance.

Mineral and Gas Pallet Locations

You can find some more pallets of Minerals in the northeast portion of the map.

In order to obtain the Cash Reward Achievement, you need to locate all of the Mineral and Gas Pallets on the map, a couple of which are right outside of your starting base location. The next set of pallets can be found to the northeast outside of a mine, and the remaining pallets can all be found at the Rebel base.

Infiltrate the Dominion Base

With your army built, have them walk into the Dominion Base unopposed.

With your army assembled full of Marines and Medics, send them forward to the enemy base with the Attack-Move command ('A' then left-click). It's best you pair a couple of Medics along with your Squad of Marines because you will encounter some Hellions on the way to the enemy base -- if not killed quickly, the Hellions will torch your infantry. That's why it's good to have some Medics on hand to keep your troops in the fight. Continue forward to the enemy base and your squad of Marines will mop up any remaining enemies as well as destroying every structure. Mission complete.
